The minimum airflow for Type I hoods used for medium-temperature appliances such as rotisseries, grills and ranges shall be determined as follows:
Number of exposed sides | Formula | |
For SI: | ||
4 (island or central hood) | Q = 100A | Q = 0.51A |
3 or less | Q = 75A | Q = 0.38A |
Alternate formula | Q = 50PD | Q = 0.25PD |
